Testimonials

  • Dr. Mayer is the most amazing doctor. I'm so lucky to have had him do my surgery. He did bilateral TKR 13 years ago on me & I am doing better than most of the people I know that had just one done at a time, even in the last few years. Most of them can't walk well on their own to this day! We are very lucky to have such a great doctor taking care of us!!!"

  • In January of 2009, I had a total knee replacement surgery done buy Dr. John Mayer of Greenleaf Orthopaedics of Libertyville, IL. My care and recovery was outstanding thanks to the surgical skills of Dr. Mayer. He is one of the most outstanding doctors I know - a man who is caring, compassionate, patient and takes the time to listen to you. I was not a number but a respected person. I have been happy to recommend Dr. Mayer several times already and will continue to do so. Greenleaf physical therapists were also a blessing in my recovery.
